Implementing Domain Driven Design
summary
Claims an actionable DDD implementation with a concrete Visual Studio solution, ASP.NET Boilerplate and Entity Framework Core projects, and a GitHub-like domain (repositories, issues, labels) that actually compiles and runs. Shows a layering model (domain.shared, domain, application.contracts, application, infra, web), enforces entity constructors enforce validity, prescribes reference other aggregates only by ID, demonstrates the specification pattern for reusable filters, advises aggregates under ~15 items, and separates domain services from application services with explicit DTO and transactional rules.
